Résumé : Since 1998 an experiment has been conducted in the Congo to evaluate harvesting methods with respect to sustainable management of eucalypt plantations. The results showed: (1) a marked negative effect on tree and stand growth when all slash materials were removed; (2) a risk of nutrient teaching after harvesting due to the high rate of decomposition of organic residues; (3) a production of inorganic nitrogen in the surface soil layer which depends on slash management; and (4) a high rate of nitrification and a risk of N tosses in the early stage of stand development.
